There are 25 students from the fifth-grade class collecting postage stamps.

Each student brought in 4 stamps, and their history teacher, Mr. Miller,
brought in 15 stamps.
Which expression could be used to find the total number of postage stamps
that were brought into class?
O A.
25 x (4 + 15)
O
B. (25 x 15) + 4
O C. (25 x 4) + 15
D.
(25 x 15)
- 4

Answer 1

C

Explanation:

there are 25 students and they EACH brought 4. Each means you multiply. so we have 25x4. then Mr. Miller brought 15 more stamps so we need to add that to the equation. so we have (25x4) because that is separate from the 15.

(25x4)+15

Answer 2

no C

(25×4)+15

because out of 25 students each students brought 4 stamps which means 25×4 and their teacher brought 15 which is added .
